Oberheim Matrix synthesizers

Oberheim Matrix synthesizers are a historic product line of analog synthesizers from Oberheim featuring a method of synthesis which Oberheim called "Matrix Modulation" as a method of defining preset and user patches. They are notable for their implementation of DCO's, which maintain a completely analog sound but are controlled by digital circuitry, making them much more stable. Matrix synthesizers continue to be popular due to their characteristic late-1980s analog sound.
